Stop rewriting the same systems for every project. Gameplay Systems Kit gives you the three things every game needs — built once, built right, and proven in a playable demo the moment you install it.

❤️ HEALTH & DAMAGE

Add the Health Component to any Actor and it just works: it auto-hooks the engine's damage pipeline, so Apply Damage / Point Damage / Radial Damage all route through it automatically. Server-authoritative and replicated for multiplayer, with optional passive regeneration (post-damage delay included). Events: On Health Changed, On Damaged, On Death, On Revived. Blueprint nodes: Apply Damage (Direct), Apply Healing, Kill, Revive, Set Max Health, Get Health Percent, Is Dead.

🖐 INTERACTION

A focus-aware Interactor Component (view trace with optional sphere radius) plus a simple Interactable interface. Focus events for highlight effects, a prompt for your UI ("Press E — Open"), and a one-call Try Interact. Input-system-agnostic — wire it to Enhanced Input or anything else.

💾 SAVE / LOAD

Slot-based save/load through a Game Instance Subsystem (Save / Load / Delete / Exists). Add a Save Component to any actor: its transform plus every property you mark SaveGame persists — on the actor AND its components. On Before Save / On After Load events let you capture runtime state (the demo uses them to save the player's camera direction).

🎯 PLAYABLE DEMO RANGE — INCLUDED

Open one map, press Play, and you drive everything yourself. No setup, no wiring:

LMB — shoot targets: floating health bars (no UMG) drop green to red, then DEAD

E — toggle switches: focus highlight + on-screen prompt

H — heal what you aim at, R — revive all targets

F6 / F9 — Quick Save / Quick Load: target health, switch states, your position and view all visibly restore

All controls are listed on the in-game HUD, and every demo actor (player character, damageable target, interactable switch, Canvas HUD) ships as readable example C++ you can copy straight into your own game.

WHY THIS KIT

✅ Zero third-party dependencies — engine modules only (Core, CoreUObject, Engine, InputCore). Nothing to rot when other plugins update.

✅ Blueprint-first — no C++ required; every property, function, and event is exposed to Blueprint.

✅ Clean, commented C++ source you can actually read, maintain, and extend.

✅ Documented — quickstarts plus per-system guides ship inside the plugin (Docs folder + README).

Works in Blueprint-only and C++ projects.
